Adaptation Phenomenon

The purpose of this study was to determine whether the decrease in stuttering which usually accompanies repeated oral readings of a passage (adaptation effect) requires the occurrence of stuttering, as is implied by almost all theories which have been advanced to explain the effect. Fifteen stutterers performed five relatively fluent readings of a 200-word passage in unison with an experimenter and a sixth reading independently. The amount of stuttering in the sixth reading was found to be essentially the same as in the sixth reading of an ordinary adaptation series by the same subjects. The inference was drawn that the adaptation effect is primarily adaptation to oral reading as such rather than to stuttering. It was suggested that the adaptation phenomenon results from rehearsal of the motor plan.

Motor Plan

Answers consistent with the anticipatory struggle hypothesis are suggested for several questions which have received a large share of experimenters' attention in recent years. The metronome effect may be due in part to the simplification of motor planning which results from reduction of speech to small units, and in part to distraction. The adaptation effect appears to be due largely to repeated rehearsal of the motor plan. An important factor in the white noise and DAF effects seems to be simply the rule that almost any novel form of auditory feedback may serve to reduce stuttering. Finally, the inconsistent effects of punishment on stuttering appear reasonable on the basis of the anticipatory struggle hypothesis when this concept is precisely formulated in behavioral terms.

The purpose of this study is to investigate students oral reading fluency of tenth grade in one of Senior High Schools in Indramayu. According to Zuhra (2015) the students faced difficulties in English because of their poor vocabulary. The students also faced difficulties when the texts were long and complicated with various different modifying phrases. There are three subskills to measure oral reading fluency. As stated by Pey, et al (2014) there are ‘accuracy’. ‘speed’, and ‘prosody’. Case study is chosen as a research method in this study. Two instruments were used to collect the data. The first is oral reading fluency test, this was used to measure students’ fluency in oral reading. The second is questionnaire. It was used to find out the students’ reading interest and reading habit. After the writers got the data. Then it will be analyzed qualitatively. The results showed that there were 36 students who took the oral reading fluency test. But, unfortunately that almost all students were not fluent in oral reading. The lowest score obtained by students in reading rate is 58 wpm. While for reading accuracy the lowest score obtained by students is 0,7 wc. And the lowest score obtained by students in reading prosody is 4. In reading prosody, almost all students get score of 4. It is because there are still many students who read only if they have to and they read not for own pleasure. Meanwhile, only two students out of thirty-six students who are almost fluent reading are able to do oral reading fluency. Have fluency in oral reading the students have practiced reading a lot. With reading rate 110 wpm and 127 wpm, reading accuracy 0,95 wc and 0,91 wc, and reading prosody are  9 of out 16.

Speech Disfluency

Each of 121 stutterers and 121 nonstutterers read a passage three times consecutively. The following types of speech disfluency were identified from tape recordings of the readings: part-word repetition, word repetition, phrase repetition, interjection of sounds and syllables, revision, and disrhythmic phonation. With the exception of revision and interjection for stutterers, the adaptation effect was observed for each type of disfluency in both groups of subjects. These data are generally consistent with the hypothesis that the adaptation effect, as it has traditionally been studied in oral reading, does not differentiate stutterers from nonstutterers.

Adaptation Phenomenon

AbstractRepeated stimuli elicit attenuated responses in visual cortex relative to novel stimuli. This adaptation phenomenon can be considered a form of rapid learning and a signature of perceptual memory. Adaptation occurs not only when a stimulus is repeated immediately, but also when there is a lag in terms of time and other intervening stimuli before the repetition. But how does the visual system keep track of which stimuli are repeated, especially after long delays and many intervening stimuli? We hypothesized that the hippocampus supports long-lag adaptation, given that it learns from single experiences, maintains information over delays, and sends feedback to visual cortex. We tested this hypothesis with fMRI in an amnesic patient, LSJ, who has encephalitic damage to the medial temporal lobe resulting in complete bilateral hippocampal loss. We measured adaptation at varying time lags between repetitions in functionally localized visual areas that were intact in LSJ. We observed that these areas track information over a few minutes even when the hippocampus is unavailable. Indeed, LSJ and controls were identical when attention was directed away from the repeating stimuli: adaptation occurred for lags up to three minutes, but not six minutes. However, when attention was directed toward stimuli, controls now showed an adaptation effect at six minutes but LSJ did not. These findings suggest that visual cortex can support one-shot perceptual memories lasting for several minutes but that the hippocampus is necessary for adaptation in visual cortex after longer delays when stimuli are task-relevant.

The individual adaptation performances of 20 stutterers under a self-formulated speaking condition and an oral reading condition are reviewed and discussed. The observations that some stutterers do not adapt under certain conditions leads to the formulation of an hypothesis concerning a research application of the adaptation effect.

AbstractThe genus Klebsiella is seemingly ubiquitous in terms of its habitat associations. Klebsiella is a common opportunistic pathogen for humans and other animals, as well as being resident or transient flora (particularly in the gastrointestinal tract). Other habitats include sewage, drinking water, soils, surface waters, industrial effluents, and vegetation. Until recently, almost all these Klebsiella have been identified as one species, ie, K. pneumoniae. However, phenotypic and genotypic studies have shown that “K. pneumoniae” actually consists of at least four species, all with distinct characteristics and habitats. General habitat associations of Klebsiella species are as follows: K. pneumoniae—humans, animals, sewage, and polluted waters and soils; K. oxytoca—frequent association with most habitats; K. terrigena— unpolluted surface waters and soils, drinking water, and vegetation; K. planticola—sewage, polluted surface waters, soils, and vegetation; and K. ozaenae/K. rhinoscleromatis—infrequently detected (primarily with humans).

In attempting to use the SEM to investigate the transition from the vegetative to the floral state in oat (Avena sativa L.) it was discovered that the procedures of fixation and critical point drying (CPD), and fresh tissue examination of the specimens gave unsatisfactory results. In most cases, by using these techniques, cells of the tissue were collapsed or otherwise visibly distorted. Figure 1 shows the results of fixation with 4.5% formaldehyde-gluteraldehyde followed by CPD. Almost all cellular detail has been obscured by the resulting shrinkage distortions. The larger cracks seen on the left of the picture may be due to dissection damage, rather than CPD. The results of observation of fresh tissue are seen in Fig. 2. Although there is a substantial improvement over CPD, some cell collapse still occurs.Due to these difficulties, it was decided to experiment with cold stage techniques. The specimens to be observed were dissected out and attached to the sample stub using a carbon based conductive paint in acetone.

Plasma Spraying Process

Plasma spraying is a technique which is used to apply coatings to metallic substrates for a variety of purposes, including hardfacing, corrosion resistance and thermal barrier applications. Almost all of the applications of this somewhat esoteric fabrication technique involve materials in hostile environments and the integrity of the coatings is of paramount importance: the effects of process variables on such properties as adhesive strength, cohesive strength and hardness of the substrate/coating system, however, are poorly understood.Briefly, the plasma spraying process involves forming a hot plasma jet with a maximum flame temperature of approximately 20,000K and a gas velocity of about 40m/s. Into this jet the coating material is injected, in powder form, so it is heated and projected at the substrate surface. Relatively thick metallic or ceramic coatings may be speedily built up using this technique.

One of the most important requirements for a high-performance EM, especially an analytical EM using a fine beam probe, is to prevent specimen contamination by providing a clean high vacuum in the vicinity of the specimen. However, in almost all commercial EMs, the pressure in the vicinity of the specimen under observation is usually more than ten times higher than the pressure measured at the punping line. The EM column inevitably requires the use of greased Viton O-rings for fine movement, and specimens and films need to be exchanged frequently and several attachments may also be exchanged. For these reasons, a high speed pumping system, as well as a clean vacuum system, is now required. A newly developed electron microscope, the JEM-100CX features clean high vacuum in the vicinity of the specimen, realized by the use of a CASCADE type diffusion pump system which has been essentially improved over its predeces- sorD employed on the JEM-100C.

Although the physiological significance of the gap junction remains unspecified, these membrane specializations are now recognized as common to almost all normal cells (excluding adult striated muscle and some nerve cells) and are found in organisms ranging from the coelenterates to man. Since it appears likely that these structures mediate the cell-to-cell movement of ions and small dye molecules in some electrical tissues, we undertook this study with the objective of determining whether gap junctions in inexcitable tissues also mediate cell-to-cell coupling.To test this hypothesis, a coupling, human Lesh-Nyhan (LN) cell was fused with a non-coupling, mouse cl-1D cell, and the hybrids, revertants, and parental cells were analysed for coupling with respect both to ions and fluorescein and for membrane junctions with the freeze fracture technique.
